Doug Schroeder Method, Double ic

@ozzy I think @douglas_schroeder tested his method with XLR-terminated balanced IC’s. Check the longer Teo Audio thread for details. BTW, that thread—like most here—goes down several rabbit holes unrelated to the thread topic. I think Doug tested the method using XLR-terminated balanced cables from manufacturers other than Teo Audio cables. 

Celander,  How do you get extra bandwidth.  You lowered the resistance with parallel conductors and upped the capacitance and induction.  I don't see any reason for the bandwidth to change just because those changed..  I get the DAC and preamp are reacting to the change in current, but I don't see that raising bandwidth.  

Unless the conclusion was changing those three electrical components resulted in a cleaner signal with less noise allowing a component to operate more efficiently and more readily reproduce higher frequencies.  But that is filtering out noise to allow better operating parameters.

What is it that you see in changing the induction capacitance and resistance that would make frequency change.

@ozzy See comment by @douglas_schroeder at the end of the above link with respect to his findings with the method using a parallel run of balanced XLR-terminated IC’s. 

Ok, I re-read it.  I gather the resistance went up, not down.  And a warning that amps may not like this.  I still see nothing talking about frequency extension or any engineering theories on how changing the electrical values passing the signal would benefit frequency extension.  

If such a simple concept as increasing mass would increased frequency then more designers would use it. I know they alter mass with speaker cables. Almost every manufacturer charges more for the better speaker cables which all seem to have heavier gauge wire. In my own personal conversations with cable manufacturers they say purity of material spacing from one another as well as shielding, construction insulation etc are the critical component to obtaining optimum sound. I doubt they would all miss added mass and not focus on that if it was relevant.

I am in no way saying Schroeder did not obtain positive results. It seems he and others have experimented with a topology and antidotal evidence is showing some benefits in their systems.  I am just wondering what the real reason for the results is. Can Improvement of the signal resulting in higher frequencies being reproduce by the amp be done in a more efficient and or cost-effective manner. Doubling up interconnect which are already expensive is pretty cost prohibitive. Especially when you need to do it between a phono, a DAC,  a CD a tape machine excetera. That's a whole lot of cable and additional Hydra head behind your gear.

celander,

Thanks for the reply, but I do not see any reference to Doug trying the double method with , just a warning.
